Amazing! Congratulations!
I had a dual NGD (NG[irl]D and NG[uitar]D) back in '07. Never getting rid of either. <3

Quote from: m-Kresol on December 01, 2016, 11:47:31 AMI have to agree. I wonder if the 400mA also includes the relays? If so, I definitely would think it may not be enough.
And I think 400mA won't do it with that number of pcbs effects.

Is it late November yet?
Quote from: madbean on November 26, 2016, 02:30:21 AMThis is actually why I don't label resistors. It gives people a chance to either do a quick Google on DigiKey, or learn them, or use a DMM. Maybe that's why I don't get too much business...
On the plus side, it's a good opportunity to learn to read resistor codes It only takes a bit of practice!
Quote from: gtr2 on November 18, 2016, 02:22:14 PMI'll dig into that at some point. I'm redesigning my PCB for the third time to keep digital and analog even further apart than I did last time. I'm also doing my best to keep ground planes super small.
As a side note. I suggest looking into digital vs analog return currents. It will improve your PCB design and you won't stress sharing a ground plane etc. There are a lot of misconceptions out there.
Quote from: sturgeo on November 19, 2016, 05:58:47 AMThis weekend I was able to 99% mute the signal when using a 10k series resistor on the audio path. That was achieved by using a relay to mute the signal. I wonder if this is all because of a breadboard. When the 10k series resistor was used with the TLP222G, I got about an 80% mute.
I can confirm that the TLP222G can completely mute the signal when used in conjunction with relay switching as described on the stompville site.
Quote from: gtr2 on November 17, 2016, 03:23:20 PMI think I just needed someone to confirm this.
None of those will fully mute your signal in that arrangement.
Quote from: gtr2 on November 17, 2016, 03:23:20 PMThis is what I think I'm going to do.
Use a relay in conjunction with the opto to stop the pop but still fully ground the signal.
Quote from: sturgeo on November 18, 2016, 12:27:50 AMIt's not THAT hush, hush. Some know about it. And until I saw the BOTY post, I wasn't keeping it as close to my vest. FWIW, I do plan on making this open source and offering a kit.
Reading between the lines i think this is what is going on but he doesn't want to give away the full schematic which is fair enough as its for the BOTY.
Quote from: sturgeo on November 18, 2016, 12:27:50 AMHis post, along with the back and forth with R.G. in DIYSB, is what I used as a basis. I just had to learn more about the technical details of these things than I ever have before.
Is the schematic for the relay & muting portion as shown here? : http://stompville.co.uk/?p=423 (about half way down the page)
Quote from: sturgeo on November 18, 2016, 12:27:50 AMYeah, I thought about doing that!
OK, if you're using the I2C bus then yes keep AGND & DGND seperate and if neccessary join them only at 1 place, i tend to put 2 pads next to each other so i can easily pop a jumper on if needs be, i'd also suggest adding plenty of filtering in close proximity to try and keep the noise levels down.
Quote from: sturgeo on November 18, 2016, 12:27:50 AMYeah, like 5 seconds!
The 222G appears to fully mute the signal when switching as i don't get any pops and the switch is more noticeable as there is a percieved silence, i'll confirm this tomorrow by editing my code and putting a much larger delay in.
